Resolution in remote sensing

Resolution in remote sensing refers to the level of detail a sensor can capture about an object's features. It determines how small a feature can be distinguished in an image. There are three main types: spatial resolution (the size of the smallest object visible), spectral resolution (the sensor's ability to distinguish different wavelengths of light), and temporal resolution (how often images are taken). High-resolution imagery shows fine details, like individual trees, while low-resolution images highlight broader areas, such as entire cities. Overall, resolution affects the clarity and usefulness of satellite or aerial images for analysis.
